Adds a new concept of "experiments" to support delivering pre-GA features over the course of multiple major Vault releases. They are designed as an opportunity to gather feedback in testing environments only, and do not come with any compatibility or migration guarantees.
Currently, there is just one experiment,
events.beta1
, for the events system to be developed behind. Note that experiments are per-node, and not persisted in storage. Furthermore, the events experiment will not touch durable storage either, but any future experiments that want to do so will need to work out how to manage the experiment's used storage on enabling and disabling.
